Three people have disappeared in Central Park over the past two weeks, leaving no evidence behind. The three victims seem to have nothing in common, so investigators have trouble finding a motive or pinpointing a suspect. Twenty-nine-year-old policeman Tomo Mihajlovi is especially frustrated until it appears he gets a break in the form of an invisible woman.

After he is bumped by something he cannot see, Tomo uses his camera with infrared and, shockingly, spots an unseen female in a dress. Of course, Tomo follows her into Central Park. Tomo saves her from two bandits, and his heroics transport him to a world of magic and creatures beyond belief.

He is in a universe parallel to ours on a Alternative Earth called Agulsa. The woman he saved is Erena Geneza, the youngest daughter of a famous sorceress. Always the investigator, Tomo explores this new, unfamiliar place, but there are still questions. For instance, why are people going missing in New York, and who plots to capture Erena?
